Hi all. I'm fairly new to the .NET platform development, so if my
question is not worded correctly, I apologize. With that said â€¦ I have been
tasked to convert a VB6 app to c#. The app has a thick VB client and
communicates via internet with database. At the first glance I was going down
the path of Remoting for communication, but than I have read couple of post
about how easy it is to reverse engineer the .NET code. Iâ€™m concerned that
now my Remote server componentâ€™s interface and location will be exposed. The
data is highly sensitive, so Iâ€™m looking for a suggestion on how to protect

Remoting over what? SOAP, binary? Why did u choose remoting?

sure, but nothing is perfect. What kinda info u wanna protect? just code?
mb look at protection of your data, not code?
..net gives u standart CryptoAPI. u can start from it.

While protecting the data is a very good suggestion, I would like to find out
how I can protect my server. This will be win app that will access a remote
server, which in turn has a direct access to database. My concern is that
somebody can get to the database through the interfaces of the server
component.

Make your connection to the interfaces protected, use Security, deny anonymouse
access and some other stuff
One example is to use Web-services and WS-E
